In a sample of 56 eighth graders, 16 chose football as their favorite sport favorite sport. if there are 495 eight graders in the school, predict the number of student who prefer football

To answer this question, first find the percentage of eighth graders in the sample who chose football. To do this, take ratio of 16/56=.285 and rounding gives us .28 or 28%. Now, if we assume that the sample size reflects the attitudes of all the eighth graders in the school, we take 28% of the total number of eighth graders (495). Doing this we get .28 x 495 = 138.6 or rounding to get 139 students. 139 students are predicted to prefer football.
